我使用以下代码来创建
XML文件：
XmlWriterSettings xmlWriterSettings = new XmlWriterSettings();
xmlWriterSettings.Indent = true;
xmlWriterSettings.NewLineOnAttributes = true;
using (XmlWriter xmlWriter = XmlWriter.Create("Test.xml",xmlWriterSettings))
{
xmlWriter.WriteStartDocument();
xmlWriter.WriteStartElement("School");
xmlWriter.WriteEndElement();
xmlWriter.WriteEndDocument();
xmlWriter.Close();
}
我需要动态插入节点,创建以下结构：
<?xml version="1.0" encoding="utf-8"?>
<School />
<Student>
<FirstName>David</FirstName>
<LastName>Smith</LastName>
</Student>
...
<Teacher>
<FirstName>David</FirstName>
<LastName>Smith</LastName>
</Teacher>
...
</School>
我该怎么做？应从键盘读取“FirstName”和“LastName”的值,并且可以随时输入值,当然在现有值下.
解决方法
你可以使用Linq Xml
XDocument doc = XDocument.Load(xmlFilePath);
XElement school = doc.Element("School");
school.Add(new XElement("Student",new XElement("FirstName","David"),new XElement("LastName","Smith")));
doc.Save(xmlFilePath);
编辑
如果要将Element添加到Existing< Student>,只需添加一个Attribute
school.add(new XElement("Student",new XAttribute("ID","ID_Value"),"Smith")));
然后,您可以向现有< Student>添加更多详细信息.通过搜索 – >得到 – >加
XElement particularStudent = doc.Element("School").Elements("Student")
.Where(student => student.Attribute("ID").Value == "SearchID")
.FirstOrDefault();
if(particularStudent != null)
particularStudent.Add(new XElement("<NEwElementName>","<Value>");
